Indian automotive manufacturers rely mainly on direct truck deliveries from their assembly plants to the customersacross the country. As India has an extensive coastline, companies should be able to develop e_x000E_cient distribution withcoastal shipping. We select a major Indian automotive manufacturer based in southern India with the major ports inIndia considered as potential roll-on/roll-oterminals to analyze the modal shift from primary road based distributionto coastal intermodal shipping. The computational study of a mathematical model along with the analysis of currentregulatory framework estimates current potential and suggests requirements for a successful modal shift.
